SPECIFICATION forming part of Letters Patent No. 735,784, datedV August 11, 1903. Y Y Application filed OctoberAlO, 1902.` Serial No. 126.809. (No model.)

To all whom, t may concern:

Be it known that VI, KATHRINE J AMIMA LAw, a citizen of the United States, residing at Merriam Park, in the county of Ramsey and State of Minnesota, eXecutriX of the estate of JOHN vLAW, deceased, late a citizen of the United States, land a resident of Merriam Park, St.

invention consistsin certain novel featuresof construction, as hereinafter shown and described and then specifically pointed out inA the claims.

In the drawings illustrative of the invention, Figure 1 is a perspective of the apparatus complete. Fig'..2 isan enlarged detached detail of the derrick-clamping mechanism. Fig. 3 is an enlarged side view, partially in section, of the rope-grip. Fig. 4 is a side view of one of the'side'plates of the rope-gri p detached. Fig.v 5 is a plan view, andV Fig. 6 is a side View, partially in section, of one of the guide-pulleysV for the draft-cable.

This apparatus may be employed for the purposeof loading wagons orcars or building stacks, and consists of a derrick-like framework erected at a suitable point adjacent to the 'place Where the wagon or car is to be loaded or the stack erected, the derrick consisting of two main side timbers or posts 1 2, spaced apart and V with their-lower ends suitably secured by stakes 4 5, or, if vpreferred, cavities may be formed in the ground in which they will rest, the obje'et'bei'ng toQso secure them as to resist lateral movement when the apparatus is in operation. The side timbers will preferably be distended at their lower ends, so that the largest possible area will be' secured between the posts for the wagon, car, or other vehicle or a stack.

Attached to the upper ends of the side posts l and 2, respectively, are struts or braces 6 and 7, trending inwardly at an angle and connected together at their inner upper ends by bolts 8, 9, and 10, passing through brace- 5; plates 11 and 12, and likewise secured to the upper ends of posts 1 Vand 2 by brace-plates 15 and 16, and further secured,preferably, by clips 13 and 14, as shown.

The parts will all be secured by bolts, as 6o shown, so that they can be readily connected and disconnected' for convenience of transportation.

Stay or brace rods or` cables 17 18 are secured to the posts 1 and 2 and braces 6 and 65 7 to stengthen the posts and braces and enable them to withstand the severe strains to which they will be subjected and also to enable a lighter quality of material to loe employed for the posts and braces. The upper 7o ends of the stays 17 18 will be secured by loops 17 n 18 therein to the outer bolts 8 and 9, by which the brace-plates 11 12 are secured, while their lower ends will be secured in the timbers 1 and 2, near their lower ends, 75 as shown at 17" 18h. Checks or struts 19 2O are arranged between the stays 17 18 and the posts 1 2 intermediate of their lengths, as shown, to hold the stays outward away from the posts to secure the necessary bracing 8o action at the lower portion of the stays, while a similar bracing action is obtained at the upper part of the stays owing to the stays passing over the upper outer ends of the posts l 2 in their course along the framework, as shown. By this means the frame is greatly strengthened and provision made for the employment of smaller-sized timbers th an if the stays were not employed.

2l 22 indicate guys provided at their upper 9o ends with eyes or loops 21 22a, respectively, adaptedV to be engaged by the bolt 10, which passes centrally through the brace-platesll 12 and the guys, thus connecting'thesanfie between theplates beneath the meeting-point of the braces G 7, as shown, while their lower ends will be secured to theground, as hereinafter described.

The derrick or framework is designed to have its upper end moved forward and backroo ward whenin operation to carry the load after it has been elevated to a point above the wagon or other vehicle or stack, and there will be play enough between the guys to permit this movement. Thus the guy 2l will be of a length adapted to support the upper end of the derriek-frame in its position above the point where the load is to be received, while the guy 22 will be of a length adapted to support the upper end of the derriek-frame in its position above the wagon, stack, or other point of discharge of the load.

The guy 2l, which is attached to the ground at its lower end by means of stake 23, is provided between its ends with a weight 24 for the purpose presently described. The guy 22, which is passed through a pulley 25, attached to a stake 2G, is provided at its lower end with hook 27, adapted to be attached to whiiiietree 28 of the draft-team, (indicated at 281,) whereby the guy is operated to swing the upper end of the derrick forward and backward, as above described. The guy 22 is limited in its travel in the pulley 25 by means of suitable preferably adjustable stops 2f) 30, thus limiting the movement of the upper end of the derrick, which is moved in one direction by draft-animals and in the opposite direction by the weight 24. The stop 29 controls the distance to which the draft-animals will move the derrick, and the stop 30 controls the point to which the weight 24 will return the derrick. Greater freedom of action is imparted to the weight by sustaining the guy 2l away from the ground through the medium of strut 231. A shorter auxiliary guy or draftrope 32 is shown coupled to the guy 22 between the pulley 25 and the point of connection with the derrickframe and adapted to be connected to the whiiiietree 2S of the draft-team. This may be employed to move the derrick instead of the extended end of the guy 22 and the pulley 25, if preferred; but the action and the results produced would be the same.

Attached to the derrick-framc at suitable points are draftline-guide pulleys 33, 15.4, 35, and 36, over which the draft-line 37 leads, as shown. 38 and 39 are two other pulleys, located below the line of the pulleys 35 315, and provided with hooks 40 4l by which they are coupled to the slings 42 or other fastening or support for the load to be elevated. The end of the draft-cable 37 is attached at 43 to the frame of pulley 15S and carried thence up around pulley 36, thence downward around pulley 39, thence through pulley 38, thence through the 1'ope-loekover pulleys 35 34 33 to the whi'letree 2Q of the draft-team, as shown.

Vhen the load has been elevated to the proper point for swinging the derriek and released by the draft-animals, a cable-locking mechanism situated between the pulleys 35 and 3S locks the cable and sustains the load until the derrick has been swung to the proper point of discharge, when a slight pull upon rope 44 will release the lock and permit the load to descend. The lock automatically engages the cable to sustain the load whenever released by the draft-animals. lhe construction of this locking mechanism is more fully illustrated in Figs. 3 and 4, and consists in two bars 45 45, connected together at their upper ends by a clip 46 and also supporting a guide-pulley 47 at tle same point, as shown. The lower ends of the bars 45 45 diverge, and the bar 45 is pivotally connected to the outer ends of a lever-arm 48, as shown. The lever-arm 48"is extended upward at its inner end, as at 49, and provided with a jaw member 50, pivotally connected thereto centrally of the jaw. Pivotally connected to the lower end of the diverging bar 45" is another leverarm formed of two members 51 51, embracing the lower end of the bar 45a by their outer ends and passing inward and likewise embracing the inner free end of the lcver-arm 4S, to which they are pivotally engaged by studs 52. Between the members 5l 5l is pivotally supported a jaw member 25, opposed to the jaw member 50 and arranged in alinement therewith, as shown. Extending from the members 5l 51 are wings 53 53", between whose upper ends a weight 54 is pivotally supported, and connected to this weight is the draw-cord 44, carried thence over the guide-pulley 47 to a point convenient to the hand of the operator, as indicated at 5e'. The opposing faces of the jaw members are concaved and alternately corrugated and adapted to inclose the draft-cable 37 in its course between the pulleys 35 and 38. By the construction shown of the lever-arms with the movable opposing jaw members carried between them when the lever-arms are moved downward the jaw members will be forcibly moved inward and very tightly clamp the draft-cable between them, as will be readily understood. By this simple arrangement so long as the draft-cable is moving upward the jaw members are ineffective; but the instant any downward movement begins the jaws will be moved downward and tightly clamp the draft-cable, the weight 54 greatly assisting in this action by adding its weight to the lever-arms. The tri p-line 44 is a means by which the weight and lever-arms are raised to open the jaws and release the cable, and also enables the locking mechanism to be supported in an ineffective position when not required by drawing the lever-arms upward andholdingthemsuspended. Theusualtriprope 5G will be employed to release the sling.

The operation is as follows: The derrickframe will be erected with the posts l 2 on opposite sides of the place where the wagon is to be loaded or the stack erected, with the guy-cables 2l 22 properly located and connected and the weight 24 and the draft-cable and lock mechanism properly adjusted. If

a wagon is to be loaded, it will be driven into proper position, with its rear part about in line beneath the upper part of the derrickframe when in its backward orload-receiving position.

Then when the load has been TTC . another load.

. elevated to the proper distance.

.the work.

gripped the team, having been hitched to the draft-cable, is started forward and the'load When the load has been elevated to a point nearly as high as required, the loose end of the guy 22 or the auxiliary draft-guy 32, as the case may be, is coupled to the whiiiletree 27, and the continued forward movement of the team will cause the derrick to be tilted over, carrying the load with it, and thus placing it in position above where it is to be discharged. At the iirst pause of the team the load will settle downward, causing the jaw members to automatically grip the cable and hold the load suspended. When the load is to be released, a slight pull on the locl-line 44 will trip the lock mechanism and release pulleys 38 39 to permit the load to descend. The weight 24 will-immediately return the derrick-frame to its former position ready for The wagon may then be adj usted to bring it in proper position to receive the balance of the load, or the location ofthe stops 29 30 or the auxiliary guy 32 may be adjusted to cause the derrick-frame to be tilted to a greater or lesser distance to adapt the dischargepoint to the requirements of The same adjustment may be employed when used in connection with a stack to cause the load to be delivered upon any part of the stack. The second bundle elevated upon the wagon does not require the derrick to swing as far as the first bundle, and instead of moving the receiving-vehicle a short auxiliary guy-cable 32 may beattached to the guy 2l just in advance of the weight 24 to limit the movement of the guycable 2l and correspondingly limit the swinging movement of the derric'K-frame, and this same arrangement can be employed in stacking .to discharge the loads upon different parts of the stack.

The pulleys 38 39 are substantially duplicates, the only difference being that the pulley 38 is provided with means' for the attachment of the draft-cable 37 as above noted. The pulleys are denotedl as a whole at 38 39, and their construction is shown in Figs. 5 and 6, each pulley being incased in a frame formed of two parts 57 57, united by tie-bolts 5S, and each with its hook 40 41, respectively, by which the opposite ends of the sling 42 are supported. Within each of the hooks is pivotally supported a trip-latch 59, the trip-latch having an extended arm 60, to which the tripline 5b' is connected. Each of the trip-latches is maintained normally closed by a sprin g 6l. The arm 60 is connected to the latch 59 at its lower end, so that any outward strains to which the latch is subjected from the sling will tend to bind it against the outer end of the hook, and thus prevent it from being accidentally released and releasable only by a pull upon the releasingcord.
